Lots of great suggestions here and +1 on the thanks for the magazine as well - very nice. I am a faculty member at a university too and have worn simple Dickies 874 work pants for years. They are tough, made of mostly polyester so they have some wicking ability and dry out rather quickly in rain, etc and resist stains from road well. I just roll them up as far as the temps dictate on any given day and then roll them down, thrown on a button down shirt and they pass pretty well at meetings. They are not as light or breathable as some of the much more expensive suggestions here, but at $27 they are a good value.
